Sulikowski s total synthesis of urdamycinone B [36] (Scheme 12.45) is characterized by C-glycosidation of a carbohydrate lactone and Diels-Alder reaction of a C-glycosyl... 

Glycosides are a large and very important class of carbohydrate derivatives character ized by the replacement of the anomeric hydroxyl group by some other substituent Gly cosides are termed O glycosides N glycosides S glycosides and so on according to the atom attached to the anomeric carbon... 

Easily available advanced synthons, such as the carbohydrates, amino acids, hydroxyacids, and terpenoids, make the synthetic task easier than the complexity metrics of the target suggests this is especially true for the glycosides, if the carbohydrate portion can be introduced intactly. It must also be borne in mind that the S metric is counted in a linearly additive hion, neglecting interactions between the functional groups (Whitlock 1998) such interactions are not treated adequately by any method so far proposed to calculate the molecular complexity. Moreover, no attention was paid here to the graphic analysis of the synthesis plan based on the molecular complexity of the intermediates these aspects have recently been reviewed (Bertz 1993 Whitlock 1998 Chanon 1998).

Solution A trisaccharide is a carbohydrate that consists of three monosaccharides. Hydrolysis breaks the glycosidic bonds between the monosaccharides and we note that D-raffinose is made up of D-glucose, D-galactose and D-fructose. We can determine the ring size and the order of the component sugars by examining the products of D-raffinose s methylation and hydrolysis. These compounds are ...
